Seasonal Experiences for Nature Lovers in the National Parks
The national parks are spectacular landscapes for nature lovers. However, some experiences can only be witnessed in specific seasons. Check out the list below for unforgettable experiences for nature lovers in winter, spring, summer, and fall.
Winter
Witnessing the northern nights, Denali National Park, Alaska

Seeing the pastel streaks and neon curtains of the aurora borealis is on many travelers’ bucket lists, best seen in the winter months of September through April. But the summer’s midnight sun is equally unforgettable, casting a glow over the landscape during long, bright nights.
Bird-watching, Dry Tortugas National Park, Florida
Dry Tortugas is a bird-watcher’s paradise, with over 200 species spotted annually. Spring brings herons, raptors, and shorebirds, while summer highlights frigatebirds and terns. Bush Key, which is closed during breeding season, hosts massive nesting colonies of brown noddies and sooty terns. Fall and winter offer hawks, falcons, and kingfishers.
Firefall, Yosemite National Park, California

Horsetail Fall on El Capitan puts on a show each year in the month of February, when the evening sun turns it into a glowing “firefall.”
Spring
Synchronous fireflies, Congaree National Park, South Carolina
Each spring, thousands of fireflies flash in unison above Congaree’s forest floor in a rare mating display. The 10 nights over which the show takes place are difficult to predict, making it all the more magical to witness.
See the cacti bloom, Big Bend National Park, Texas

Big Bend boasts more cactus species than any US national park—over 17 in all. From blooming prickly pears to adorable claret cup hedgehogs, these resilient desert plants add bursts of color to the arid landscape, especially dazzling in April.
Summer
Spotting humpback whales, Glacier Bay National Park, Alaska

In the summer months, majestic humpback whales gather in the nutrient rich waters off Glacier Bay’s 700 miles (1,130 km) of coast, feasting on up to 3,000 pounds (1,360 kg) of small fish and krill per day. Join a guided tour for a chance to spot orcas, minke whales, and sea otters through binoculars, or even hear them through the boat’s hydrophones.
Star Party, Voyageurs National Park, Minnesota
Certified as a DarkSky International park, Voyageurs’ night skies put on a dazzling show. Nights can offer brilliant stars, along with the chance to see the northern lights. Come in late Summer for the Star Party, a series of free astronomy events, and take a nighttime paddle in a canoe to see the stars.
Witnessing the great caribou migration, Gates of the Arctic and Kobuk Valley National Parks, Alaska
In late summer and early fall, hundreds of thousands of caribou travel from their summer calving grounds to the south. It’s a natural marvel that’s been closely watched by humans for thousands of years—the Iñupiat people still hunt caribou much as their ancestors did. Guided trips and air taxis provide safe access to this spectacular wildlife event in both parks.
Fall
Salmon run, Olympic National Park, Washington

In September and October, Chinook and coho salmon, steelhead, and cutthroat trout leap from the Sol Duc River on the Olympic Peninsula, swimming upstream to spawn. At Salmon Cascades, platforms offer close views of this dramatic spectacle, an unforgettable glimpse of nature’s power and resilience.
Wildlife-watching on Gold Bluffs Beach, Redwood National Park, California
The driftwood-strewn shore of Gold Bluffs Beach is not only hauntingly beautiful—it also offers prime wildlife-watching. Bring binoculars to spot harbor seals, seabirds like the charismatic (and threatened) snowy plover, and even Roosevelt elk grazing near the dunes. In spring and fall, keep an eye out for migrating gray whales just offshore.
Watching the elk rut in the fall, Rocky Mountain National Park, Colorado

As the aspens turn golden and the fall air crisps, bull elk bugle across the valleys during the autumn rut. From September to October, males gather their harems, and their primal calls can be heard at dawn and dusk. Watch safely from roads near Moraine and Horseshoe Parks, where foot access is restricted to protect wildlife.
